School Management System DFD Levels 0 1 2 | Dataflow Diagram Best of 2021
Hi there Itsourcecoders! Today I will give you ideas about the School Management System Project DFD Diagram levels 0 1 2. This PDF will also give you deep understanding about School Management System Best Data Flow Diagram (DFD) levels 0, 1 and 2 2021.
Here’s what you need to know.
The Data Flow Diagram (DFD) represents the flow of data and the transformations in School Management System. In the DFD, input, processing, and output are used to represent and define the overall system.
The following are the flows that the School Management System can generate:
- Manage Students’ Information
- Monitor Enrollment/Enrollees’ Transactions
- Manage Teachers’ Information
- Manage Courses’ and Subjects’ Information
- Checks Student Year Level and Status
To have an advance knowledge about the School Management System, you must be familiarize with these symbols:

Here’s the Dataflow Diagram levels 0 1 2 for School Management System and step-by-step way on how to create School Management System DFD.
- School Management System DFD Level 0
To start with, let us familiarize what is School Management System DFD level 0.
The School Management System DFD level 0 is also known as context diagram. It’s supposed to be an abstract view, with the mechanism represented as a single process with external parties.
This DFD for the School Management System depicts the overall structure as a single bubble. It comes with incoming/outgoing indicators showing input and output data.
In this data flow diagram you will see the general process done in School Management System monitoring. This will also serve as a guide as you go through the deeper processes of the School Management System data flow diagrams.
As you see, when you build the levels of data flow diagrams, the connections of the transactions and data also broadens and gets more specific.
- School Management System DFD Level 1
Next to the context diagram is the level 1 data flow diagram.
The content of School Management System DFD level 1 must be single process node from the context diagram and is broken down into sub processes
In this level, the system must display or reveal further processing information.
The following are essential data to accommodate:
• Student Records
• Enrollees Records
• Courses Records
• Enrollment Request
• Instructors Information
These procedures require information such as record of students, enrollees, transactions and instructors from which served as the bases for the school admin to manage the School Management System. This type of data is represented by a data store.
With being knowledgeable about the DFD level 1 of the School Management System, you will know then its broaden context terms.
In addition to that, this may also serve as your reference on how the inputs or data fed on the system. Then you will be also informed about the outputs that the system gives.
These processes shown in the DFD were all based on the concept of School Management System.
- School Management System Level 2
After presenting the School Management System DFD levels 0 and 1, next to that is level 2.
Here’s what you need to consider in creating data flow diagram level 2 for School Management System.
• The Level 2 DFD for the system should represent the basic modules as well as data flow between them.
• Since the DFD level 2 is the highest abstraction level, its School Management System processes must be detailed that is based on the DFD level 1.
Finally, after figuring the processes given in the system, the user will now have their request being processed.
The Processes that the system should prioritize are as follows:
• Manage Students’ Information
• Monitor Enrollment/Enrollees’ Transactions
• Manage Teachers’ Information
• Manage Courses’ and Subjects’ Information
• Checks Student Year Level and Status
Additional Knowledge on DFD Levels 0 1 2 of School Management System.
What is School Management System context or DFD level 0?
A context diagram is another name for it. With the mechanism represented as a single process and external parties it will be an abstract view. It depicts the overall structure as a single bubble with incoming/outgoing indicators showing input and output data.
The data flow diagram level 0 also considers the entire system to be a single process and emphasizes the system’s interaction with external entities.
What does School Management System level 1 DFD entail?
The System level 1 DFD lists all of the major sub-processes that make up the entire system. A level 1 DFD can be thought of as a “detonated view” of the context diagram.
A single production node and its relationships to external entities are depicted in Level 0 data flow diagrams. Level 1 DFDs provide a broad overview but go into greater depth than a context diagram.
The single process node from the context diagram is broken down into sub processes in a level 1 data flow diagram.
What does School Management System level 2 DFD entail?
The 2-level DFD delves even deeper into the concepts of 1-level DFD. It can be used to plan or record all of the specific/necessary information about how the system works.
Level 2 DFD is the DFD’s highest abstraction level and represents the system’s basic modules as well as data flow between them.
So that completes our discussion fellas! And I hope that this PDF about School Management System Project Data Flow Diagram Levels 0 1 2 | Best DFD 2021 will help you a lot.
